Description

  The present invention generally relates to electrical connectors. More specifically, the present invention relates to an electrical connector having a clamp that provides strain relief to a wire connected to a contact (or contact) housed within the connector.

  Electrical connectors for mechanically and electrically interconnecting groups of individual electrical conductors (such as wires or cables) are well known. The wire is terminally connected (or terminated) to a contact in the connector. In many applications, for example, when removing a connector, tension may be applied to the wire, which can adversely affect the connector. By tension, one or more wires may be pulled from the contact and / or disconnected from the connector.

  It is well known in the art to use strain relief (or strain relief devices) on the electrical connector that terminates the wire or cable to minimize stress in the wire or cable. To prevent the wire from being cut (or disconnected) or damaged, strain relief prevents the force applied to the wire from being transmitted to the contact that terminates the wire.

  Typically, the strain relief device has separate members that can be secured around the housing and wire. The individual members may be secured together by various methods such as external hardware or an interlock function. Attaching the strain relief to the connector requires placing the connector and wire on one of the strain relief members and then securing the individual members of the strain relief device together.

  Accordingly, it is an object of the present invention to provide an electrical connector having a strain relief that is simple and inexpensive to manufacture and install, but is extremely effective in preventing the force applied to the wire from being transmitted to the contact. That is. It is a further object of the present invention to tighten the strain relief so that it does not move axially relative to the connector, thereby providing a smooth (or flat) interface (or flat) between the strain relief and the connector (or Contact surface). In addition, a further object is to provide strain relief for cables of various diameters using the same strain relief element while maintaining a smooth external transition between the elements of the strain relief device.

  An electrical connector for terminally connecting wires housed in a cable has a housing including contacts and a cable clamp attached to the housing. The cable clamp has an intermediate piece, a rotating clamp rigidly attached to the intermediate piece, and a cable retaining finger disposed within the rotating clamp. The cable retention fingers may be integral with the intermediate piece or may be provided as a separate element. The rotating clamp is configured to apply a force to the cable retention finger, which provides strain relief to the cable, thereby causing the wire to physically and electrically disconnect (or break) under nominal operating conditions. ) Is prevented.

  A strain relief clamp is disclosed having an intermediate piece, a rotating clamp rigidly attached to the intermediate piece, and a cable retaining finger disposed within the rotating clamp. The cable retention fingers may be integrated with the intermediate piece or the cable retention fingers may be provided as independent elements. The rotating clamp is configured to apply a force to the cable retention finger, which provides strain relief to the cable to keep the wire physically and electrically disconnected (or disconnected) under nominal operating conditions.
